Nowadays, communication technology is increasingly used in Chinese Train Control System. And the Railway Signal Safety Communication protocol is the upper layer protocol that ensures safety transmission of safety related information in a non-trusted channel. The characteristics and behavior pattern of the protocol are closely related to the safety of the whole railway signal system. This paper simulates...
Modeling aims to reduce the time to design and to manufacture. This is especially true for real-time applications. Transportation is one of the most constrained areas for these applications. Thus, any designed system must be modeled and verified in order to prevent troubles and dysfunctionings. In addition, in the transportation area, a lot of embedded devices are used. Then efficient communications...
This paper concerns the design and verification of a realtime communication protocol for sensor data collection and processing between an embedded computer and a DSP. In such systems, a certain amount of data loss without recovery may be tolerated. The key issue is to define and verify the correctness in the presence of these lost data frames under real-time constraints. This paper describes a temporal...
